3.4.50 –lx

Add library libx.a to linker’s list of search
libraries.

Pass -lx to the linker to specify additional libraries for ld to
search for unresolved references. ld links with object library libx.
If shared library libx.so is available (and -Bstatic or -dn are not specified), ld uses it, otherwise, ld uses static library libx.a. If it uses a shared library, the name is built in to a.out. No space is allowed between -l and x character strings.

Example: Link with the library libVZY:

demo% f95 any.f -lVZY

Use -lx again to link
with more libraries.

Example: Link with the libraries liby and libz:

demo% f95 any.f -ly -lz

Programming Guide for information on library search paths and
search order.
